Whether it’s subtle seepage or a more obvious leak, moisture can lead to serious building damage and even affect the health of the people living inside.
Common Problems Caused by Moisture
Unchecked moisture can cause a variety of issues, including:
Structural wood rot
Mold and mildew growth
Foundation shifting or cracking
Corrosion of metal components
Ice dam formation
High indoor humidity and condensation
Mold, in particular, is a major concern. It can cause respiratory problems and allergic reactions, especially in individuals with asthma, allergies, or compromised immune systems.
How Moisture Gets Inside
Moisture enters the home in several ways:
Air leaks: The most common way moisture gets in. Warm, moist air can enter through gaps and cracks in the building envelope.
Diffusion through materials: Though slower, water vapor can still move through porous materials.
Roof and plumbing leaks: Common culprits that allow bulk water in.
Flooding or seepage: Can be seasonal or due to rising groundwater.
Daily activities: Cooking, bathing, and even houseplants release moisture into the air.
Moisture Risks Vary by Region
In colder northern climates, high indoor humidity in winter can lead to condensation problems. In hot, humid areas, the issue is reversed—warm, moist outdoor air meets cool interior spaces. South Jersey homes often face both, depending on the season.
